I have a Presario CQ62-306AU notebook with a damaged hard drive that still works after a fashion in safe mode. It currently has a 320 GB 5200 SATA HD that I wish to replace with a 750 GB 7200 drive.The repair manual says it will support a 750 GB 5200 HD, but also that the only 320 GB HD it supports is a 7200 whereas my current HD is a 5200. A bit confusing.Does anybody have any idea if it will support my preferred option of 750 GB 7200 drive?

If you could live with less storage a 240 to 256 gig ssd would be the way to go (their coming down in price quite fast) if your system could run them. I put an SSD in a six year old HP laptop, and now it runs really great. Just a thought.
